PowerPoint Multimedia Presentations in Computer Science Education: What do Users Need?

PowerPoint Multimedia Presentations in Computer Science Education What Do Users Need? Elke I. Reuss, Beat Signer and Moira C. Norrie Institute for Information Systems, ETH Zurich 8092 Zurich, Switzerland

Motivation

PowerPoint is one of the most commonly used presentation tools

Little is known about user needs for delivering lectures with PowerPoint

Our goal: investigate these user needs and develop an enhanced PowerPoint based presentation tool

Study Design

9 computer science faculty members, age 25-62

ETH Zurich and University of Zurich

Method

structured interviews (on average 37 minutes)

collected a sample presentation from each participant

Questions

status quo of PowerPoint in lectures

does PowerPoint satisfy the user needs or what additional functionality is desired

Setup

Hardware

laptop (n=8) and tablet PC (n=1)

pointing device: laser pointer (n=7) or stick (n=1)

remote control (n=6)

Software

PowerPoint 2007 (n=4), PowerPoint 2004 (n=1) and PowerPoint 2003 (n=4)

All participants use PowerPoint since more than 7 years

Results

Content and Organisation

all participants sort the slides in the order they intend to present them

most participants (n=8) access the slides in a linear order

min max mean number of slides Results

Content and Organisation …

most participants (n=8) use extra slides

filed at the end (n=6)

filed as hidden slide (n=2)

stored in separate file (n=2)

% text formulas graphics type of content Results

Presenting Information

All participants like to move around during a presentation

Most participants use additional types of media

black-/whiteboard (n=9)

overhead slides (n=7)

videos (n=6)

software/application demos (n=2)

flipcharts (n=1)

Results
